If you use a hose that is submerge in the fluid how can it suck air back into the system, especially uphill, instead of having the container above the bleeder screw where air can get back into the hose from above?
Theory is one thing, reality is another work
I wish I had a old time pressure bleeder now instead of using a vacuum bleeder like I do now whiney
